Using too many cliches in a story will annoy your reader. An editor/judge wants to read something fresh. He doesn’t want to read that Mabel was feeling sick as a parrot, or that she made it to the bathroom in the nick of time. Nor does he want to know that she lost track of time, felt as weak as a kitten and as if her illness lasted an eternity.
Hopefully you’re starting to get the picture…
